Goal:
To review for the final using the various equations learned throughout the semester to determine various properties
of a cart colliding with a brick. Properties that will be found include:
Acceleration, Velocity,Kinetic Energy, Momentum of cart, Impulse at collision, Work Force, and Power.
Procedure:
1. Set up a track to measure the distance the brick moves.
2. Push the cart ith enough force to move the brick about 3 cm.
3. Use sensors to measure velocity and acceleration of both the cart and the brick.
4. Use data like masses and accelerations to find the force necessary to move the brick 3 cm.
Data:
Mass of brick: 1.814 kg
Mass of Cart: 1.059 kg
Equations:
*= Change in variable
velocity = *d / *t
acceleration = *v / *t
acceleration = F / m (kg)
Force = m x a
momentum = m x v
Impulse = F x *t
Kinetic Energy = (1 / 2) x m x (v x v)
Work = F x d x cos (Angle)
Power = Work / t
Calculations:
Acceleration of Cart: 9.849 m/s/s
Acceleration of Brick: 0.1261 m/s/s
Kinetic Energy of Cart at 0.2 seconds: 0.5 x 1.059 x 1.934 x 1.934 = 1.98 J
Momentum of cart: 1.059 x 1.934 = 2.05 kg x m/s
Impulse at collision: -2.05 kg x m/s
Work of Cart: 10.43 x
Force of Cart: 10.43 N
Force of Brick: 0.2287 N
Power:
